اثرات واقعی کنترل سرمایه: شواهد در سطح شرکت در یک آزمایش سیاسی

This paper evaluates the effects of capital controls on firm-level stock returns and real investment using data from Brazil. On average, there is a statistically significant drop in cumulative abnormal returns consistent with an increase in the cost of capital for Brazilian firms following capital control announcements. Large firms and the largest exporting firms appear less negatively affected compared to external-finance-dependent firms, and capital controls on equity inflows have a more negative announcement effect on equity returns than those on debt inflows. Overall, the findings have implications for macro-finance models that abstract from heterogeneity at the firm level to examine the optimality of capital control taxation.
